On commercial vehicles and trucks, it is often needed to provide power to bodybuilder equipments. Indeed, such vehicles are often provided by the vehicle manufacturers as only a chassis equipped with a driver's cabin and with the driveline and powertrain. Such chassis is to be equipped by so-called body builders with various bodies or more generally with various equipments specifically suited for a defined application. Body builder equipment can include various types and forms of cargo areas which can include various tools and equipments. Some of these tools and equipments need energy to operate. Such equipment include powered tailgates, tippable platforms, cranes and hoists, concrete mixers, garbage compactors, etc. . . . The energy needed to power such equipment is quite high, so that in conventional vehicles, it cannot be provided by the conventional on-board electric circuit and is necessarily provided through a mechanical power take-off powered by the internal combustion engine.
